Accuphase C-47 Phono Equalizer AC100V made in Japan

A top-of-the-line phono equalizer with a fully balanced configuration that pursues the ideal.

The C-47 is the first high-end phono equalizer amplifier in the series to achieve a fully balanced configuration from input to output. In addition to adopting a balanced configuration that is resistant to external noise, we have achieved extremely low noise and highly accurate RIAA deviation by using a dedicated MC/MM head amplifier and high-precision equalizer amplifier that are optimized according to the characteristics of the cartridge. . In addition, by newly equipping the MC with a dedicated phono balanced input terminal, it supports balanced connection with analog players equipped with balanced output. The C-47, which fully expresses the charm of the cartridge, will deliver a deep impression.
